To all whom 'it may concern: I

Be it known that'I, ELIEL L. SHARPNECK,

of Winthrop, in the county of Suffolk, State of Massachusetts, haveinvented certain new and useful Improvements in Starting Devices forInternal-Combustion Motors, of

- which the following is a full, clear, and exact specification,reference being had to the accompanying drawings, forming part thereof.

This invention relates to improvements in" internal combustion motorsand has refer ence particularly to devices designed to effeet thestartin of such motors.

The object this invention is to provide means, for dischar ing into aninternal'com-. bustion motor a cfiargeof fluid under press'ure-toefiectthe initial movement of one or more of itspistons. f p v I The inventionconsists in such peculiar features of, construction and combinations Iof parts as shall hereinafter be morefully described and pointed outintheclaims.

Figure 1, irepresents aside elevation of parts 'of an internalcombustion motoncf well known construction shown in relation 7 tothegdash board ofa vehicle'and as combined' withthe improved startingmechanism. Fig. 2, represents a reverse. view of trolling valve for thesupply pipe of the startin device with its actuating cam.

Simi ar characters of reference designate corres ondingparts throughout.I

As s own in the drawings 9-represents the casing of any well known motormechanism designed to be operated by fluid compression "and particularlyany well know internal combustion engine having one or morecylinders-each furnished with the usual movable iston. Suitablegas'eousfluid being sup hed to-said cylinders through-pipes 10 an 11 andthe unconsumed gases being delivered from-said cylinderstothepipes 12and 13 tothe'exhau'st pipe 14. I

' carrying this. invention into practice I provide the exhaust pipe orchamber 14 with -valve 17 designe some of the parts shownin Fig. 1. Fig.3,

the branch outlet 15 having a valve seat at its inner end. Journaled inbearings in the wall of the chamber 14is the shaft 16 having at itsinner .ortion the beveled edge at times, to close said chamber 14'and"furnished with the valve stem 18 carrying the conical valve 19 adapted,when the valve 17 is in the open position, to close the outlet 15. Theouter end of the shaft 16 is supplied with the'collar 20 having the camface 21 and arm 22 and the arm 23, normally retracted by spring 24,secured are normally positioned as shownin Fig.6.

to said arm and to a fixed portionv of the chamber 14, whereby thevalves Hand 19 7Q Theoutlet 15 is preferably connectedwith the casing 25of any well known check valve and said casing 25 is connected by thepipe. 26 with the pressure tank 27 located in any desired position andhaving the outlet 28 which communicates through the valve chamber 29with the pipe 30 connected with the fluid delivery pipe. 11. Valvechamber 29 is furnished with the usual check valve 31 having'thespringlretracted valve stem 32 the outer end 'ofwhich is roundedsomewhat. In addition to the outlet pipe 28 the tank 27" is preferablyfurnished with the ,pipe 33 communicating with thewell known pressuregage '34ilocatecl at any convenient point but herein shown as mounted onthe dash board D of a'vehicle;

Mounted on the dash board D, or on anysuitable. support, is the plate 35having the having a roller bearing which is located between the cams 21and arm 22 of collar 20.

When the motor is operating under normal conditions the parts are in thepositions shown in full lines. If now the operator desires to storefluid under compression, for

use in restarting, opportunity is taken at a -time when the motor is notunduly loaded as, in case of a vehicle driven by said motor, I

when such vehicle is descending an incline,

to shut oil? the sparking mechanism whereupon the motor will run, bymomentum, as a compressorand will force the compressed whilethe rotationof shaft 40, by such 'movement of arm 41 swings the arm 44 the rollerbearing of which acting against cam 21 effects the swinging of said cam,against the action of its spring24, and the partial rotation of theshaft 16 to bring valves 17 and 19 to the positions shown in. dottedlines in Fig. 6 whereupon the compressed gaseous fluid forced outward bythe operation of the motor will pass through the outlet 15, check valve25 and pipe 26 to tank 27. When the gage 34 indicates that the pressurewithin the tank 27 is suitable the operator swings handle 41 back tonotch 39 and thus releases cam 21 which swings back to its normal position under the retractive strain of the spring 24 to efleet theclosing of valve 19 against its seal and to open valve 17. At thistime-the check valve in casing 25 will prevent the escape of gaseousfluid through pipe 26' and outlet 15 while the valve 31 will prevent theescape of such gastthrough pipe 30. The operation of restartingv themotor is extremely. simple and is accomplished by swinging lever handle41 to notch 38 where; by the shaft 40 is rotated to brin its cam 43 tobe against the end of the va ve stem 32 and to press inward said stemand open 'valve 31 to permit the passage of the gaseous fluid, stored intank 27, through pipes 30 and 11 to the motor-9 to effect the initialmovement of said motor until it reaches a point at which the charge offluid is exploded. The subsequent operation of the motor being in theordinary manner. It is obvious that this starting device can be appliedto a stationary motor of'the nature described.

Havingthus described my invention I claim as new and desire to secure byLetters Patent.

1. The combination with an internal combustion motor having an exhaustfurnished with two outlets, of a valve movably mounted in said exhaust,for controlling the flow of fluid therethrough, and a second valveactuated by the opening movement of said first mentioned valve to closeone of said outlets.

2. The combination with an internal combustion motor having an. exhaustpipe furnished with a branch outlet, and a storage tank connected withsaid outlet of a shaft journaled in said exhaust pipe'and having a valvemember designed to close said branch ()lllltifet, andmeans'forlop'erating said valve s a t.

3. The combination-with an internal combustion motor having an exhaustfurnished with a branch outlet, a tank ,connected with said outlet'andwith the ,flu-id' supply-pf said motor by a pipehaving a normally closedvalve, of a duplex valve within saidtexhuast and having an actuatingmember extending from said exhaust, and rotatable means for operatingsaid valve actuating means.

4. The combination with an internal com bustion motor having an exhaustfurnished said valve shaft and having a cam, of a shaft journaled inbearings and having means adapted to act res ectively against the valve:stem of the supp y valve and against said cam of the exhaust valve shaftarm to actuate said members against the pressure of their respectivesprings.
